Hair for a young mummy

I had my first baby in august and love been a mummy!

however having battled with depression for years and still am now i hate the whole frumpy horrid look im getting its very shallow but its bringin me down!

does any one know of an easy but sexy hair style/colour to keep my spirits up my parner interesteted and to make me feel and look amazing if im going out or for a special occasion (eg her baptism)
but can easily be swept back in the day time when im on mummy duty?

thanks
